HANGING cenaines-BODY.jA

Specication of Letters PatentNo. 8,236, dated July 22, 1851.

. To all whom it may concern: l

` longitudinal section; Fig. 3 a top View `of the bottom of the carriage showing the position of the stop-lever when unlocked, its position when locked, being shown by dotted lines.

The same letters on the several figures indicate like parts. n j

To enable othersskilledin the art to make and use my invention, I willproceed to describe its construction and operation. j

On .the underside of the body of the carriage and parallel` to the rockers thereof, and attached thereto, are `placed on eachside, plates A A between which` plates are placed `the shafts B, C; on the center of each of `the shafts B, C, are arms D D; `also `upon the right hand end of the shaft B is turned -an arm D2, and uponthe left hand endof theshaft C another arm D3.

The bent bar E, Fig.` 2, forming the front portionof perch is connected with the front shaft B at the center thereof. n n 1 The cross bars F, forming the rear end of the perch, are united to the shaft C near the ends thereof, also being connected; at their `juncture by a bar `Gr which is joined to the shaft C at its center. The hind-axle Q, is attached to the ends of the cross bars F by a joint admitting of a slight motio-n, the

front-axle R connected by a body bolt passing through the end of the single bent bar E forming the perch. Near the junction of the cross bars F is placed a platen T with an eye in it, and there is also an eye at the end of the arm D onthe center of the shaft C.;

Through the said eyes passes the rod H having a hook upon one end anda screw oper# ated upon by a nuton the other end, intended to produce greater or less tension on-the helical spring I. There is also a rod Y,

having a hook on its end, uniting the front end of the bar E with the arm D on the center of the shaft B. The helical spring I is `suspended between the arms D D on `the rod" J which rod has a hook at oneend uniting it with the hook on rodI-I. The other end l Witnesses:

Z Z` are bent so as to embrace the helical `spring between its sides and united to the `cap m, intheform of a stirrup.`

j The lever-plate M is placed across and seof said rod J, united to the cap K, form-` ing one end of the helical spring. The rods cured tothe under side of the body, by a bolt passing through the body of the carriage. The use of this compensating lever is to pro` duce simultaneous action upon both ends of the helical spring, any weight upon one end r'of the carriage.beinglcommunicated to both ends of the spring at the same time, and is operated upon by the arms D2` D3 upon the shafts C B by rods N N.

The stays O, O, are to prevent the axles from turning by the depression of the body, thus preserving the set of the axle, and are united `bot-h to thebody and axles by joints admitting of slight motion.

j Fig. 3 represents the body in itsproper position and shows the posit-ion of the stop lever I), united to the lever M by the bolt at the center` of said lever M. The object `of this lever is that by the introduction of a pin at Qzinto the floor of the body, the spring will be arrested` from its action, and the raising of the body prevented when relieved of the weight. If it is desired to `have the body low for convenience in getting in or out, the pin isl inserted, thus arresting the lever at the dotted line until ready to start, when it is to be removed.

I-Iaving thus `fully described my invention,

what I claim therein as new, and desire to `secure by Letters Patent, is-

l. The combination hereindescribed of the turning compensating plate M, with the rock shaft B C, and the connecting rods N, for the purpose of equalizing the action on the helical spring I.

2. I claim the stop lever P, in combination with the turning plate M, used in fastening downthe body, substantially in the manner herein described.

3. I claim the stays O, O,`for thepurpose ofkeeping the axle-trees in their true set or upright position, as herein described and fully set forth. j

Y In testimony` whereof lI have hereunto signed my name before two `subscribing witnesses.` f
